Miss Daisy is about 13 weeks old we think....we got her the week before Christmas and was told she was 8 weeks old. That was not the truth! We think she was maybe 5 weeks. We had to put her on kitten formula for several weeks and nurse her along. Its been a long time since we've had a kitten and I just didn't realize how young she was. Our other cat Ninja took right to her and is teaching her all about being a cat though. Miss Ninja though only comes in to inspect when i am not working.
